And -- spoiler alert -- Nashville talent played a part. (Since we don't want to spoil the outcome for folks who haven't gotten to their DVR yet, check after the jump for more.)
Vandy guy Patrick Thomas came out strong for Music City, earning praise from all the coaches for his deep, emotive take on Tim Nichols and Craig Wiseman's Tim McGraw-sung hit "Live Like You Were Dying." The most effusive praise came from a seat that might've surprised country fans.

"That's what I'm talkin about -- exactly," soul-pop star Green said of Thomas' performance, after being the first coach to turn his chair around. (Coaches listen to the performance with their backs turned, and only about-face after they've hit a button indicating interest in adding the singer to their team for coaching.) "...I must say that song belongs to you."

Ultimately, country star Shelton won Thomas' team interest with a convincing argument: "I have the avenues to make you a country star," he said. "... I can do it."

Team Shelton also snagged the night's only duo contenders: Nashville husband-and-wife team Elenowen.

Elenowen-ers Josh and Nicole Johnson performed The Swell Season's "Falling Slowly," earning some entertaining raised eyebrows from the coaches who, backs turned, were thrown by the supple female voice turning into a breathy male one.

"I thought it was going to be one person and then a dude came in, I was like, 'What the hell is going on?'" Levine said. "I was like, 'She's a genius!'"

Once again, Shelton -- the first to turn around this time -- made a smart play and snagged the talented Nashvillians.

"First and foremost, nothing needs to get in the way of y'all's relationship, and this business is tough when it comes to things like that," said Shelton, who'll soon marry fellow country star Miranda Lambert. "I've seen it, and I know how to help y'all protect that."

Belmont guy/Texas native Jeff Jenkins' nimble, powerful voice earned some of the most excited coach responses of the night, as he performed Rascal Flatts hit "Bless The Broken Road."

"I've never heard that song but I'm pretty sure no one can sing it as well as you just did," Levine said of the performance.

All four coaches hit their buttons, though Shelton was the last to do so. That -- and the fact that Levine angled really hard for Jenkins' favor -- might have convinced the young singer in the end to choose Levine's team.
